Continuity mistake: After Lois accuses Stewie of peeing on the carpet, he asks her to bend down and slaps her with a glove. The glove remains in his hand in that cut, is still there when there is a wide shot of Peter, Stewie, Lois and Brian (you can just see it next to his trousers in his hand), but when it cuts back to Stewie and he starts on about "the outrages" etc, it is gone (the cut is instant, no time for him to put it back in his pocket). A common error, this one just struck me as strange, because the sandwich Stewie threw at Lois is there the entire scene.

Continuity mistake: When Stewie has been picked up by Lois and is being kissed by her, Brian freaks out. When you first see Stewie and Lois, Stewie's hands are on her shirt, next shot, they're on her arms.

Lois: Hello?Peter: I can't take the trash out today, I'm working late at the office.Lois: The caller ID says you're calling from the kitchen. In fact I can see you.Peter: [Edging sideways.] OK, can you see me now?Lois: No.Peter: Now I am at the office.

They're in the Clam complaining that they can't drink when they make the revelation that Brian can because he's technically 56. But Quagmire should be able to drink, as in a much earlier episode, he's revealed to be over 60.
